Which action allows a network engineer to limit a default VLAN from being propagated across all trunks?

A.
Upgrade to VTP version 3 for advanced feature set support.

B.
Enable VTP pruning on the VTP server.

C.
Manually prune default VLAN with switchport trunk allowed vlans remove.

D.
Use trunk pruning vlan 1.

Explanation:
Manaully pruning the default VLAN (1) can only be done with the “switchport trunk allowed vlans remove” command. VLAN 1 is not VTP pruning eligible so it cannot
be done via VTP pruning. The “trunk pruning vlan 1” option is not a valid command.
